The city of Chang'an was bustling with traffic and prosperous.

The power of the border governor continued to expand, and An Lushan had a large number of troops and high aspirations. Yang Guozhong and An Lushan competed for power and did not give in to each other. The party struggle in the court was fierce, and loyal ministers and generals struggled to survive in the whirlpool of power.

The Anshi Rebellion broke out, and the war swept across the Tang Dynasty in an instant. The people were plunged into dire straits, the prosperous age collapsed, and various forces competed in the troubled times. The fate of countless heroes and heroes was rewritten from then on.
